Right, just came back and started the installation, so it's work in progress, typing from the car.
However, really nice guy at the parts department, got a really good deal. The KE283-CDU01 was £197.88 and the BT adapter was £98.76. So the total came to £296.74 including VAT. Got everything for £200.00 cash!
Here is what I've done so far:
Step 1
Disconnect the battery.
Step 2
Locate the central console lid, LOL
Step 3 - optional
If you have SatNav installed the remote & the holder should be fitted inside the glove box. Remove the remote and the screws from the remote holder.
Step 4
Remove the small lid so you can get access to the wires / connectors
Step 5
Pull the seats towards the dashboard as much as possible and locate the two big screws in the center console, unscrew them, one on each side.
Step 6
Remove the ashtray and unscrew the big screw underneath.
Step 7
Carefully pull the plastic where the gear lever and aircon console is.
Step 8
Unscrew the two big screws as per photos.
Step 9
Remove the white band cable carefully.
Step 10
Pull the central console away so you can access the connections required.
Step 11
Locate the harness connectors and connect them to the two connectors from the bluetooth cradle.
Step 12
Fit the false floor back on to the central console using the screws provided in the bluetooth kit.
In case you have the older SatNav with the remote control, fit the remote holder back on the central console.
Step 13
Now go to the glove compartment behind the passenger seat and remove the carpet trim and the floor panel where the SatNav CD-ROM unit is installed.
Step 14
Locate the two harness connectors and connect the control unit.
Step 15
Peal the adhesive pads protection and stick the control unit under the glove box flooring. The fit everything back.
Step 16
Tidy up inside the car and re-connect the negative terminal of the battery.
Step 17
Now start the car and on your phone search for a new bluetooth device, pair with the 350Z using the pin: 1234. You are now ready to go!
Hope that helps!
